Safety Precautions - FlowLine Switch-Pro LC10 Series Manual

Safety Precautions

About This Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS
PRODUCT. This manual includes information on three different models of Compact Relay Controllers from
Flowline: LC10 and LC11 Series. The LC10 series is a single-input controller with an optional Flash Alarm
and the LC11 Series is a dual-input controller. Many aspects of installation and use are similar between
the three models.
User's Responsibility for Safety: FLOWLINE manufactures several models of controller, with different
mounting and switching configurations. It is the user's responsibility to select a controller model that is
appropriate for the application, install it properly, perform tests of the installed system, and maintain all
components.
Electrical Shock Hazard: It is possible to contact components on the controller that carry high voltage,
causing serious injury or death. All power to the controller and the relay circuit(s) it controls should be
turned OFF prior to working on the controller. If it is necessary to make adjustments during powered
operation, use extreme caution and use only insulated tools. Making adjustments to powered controllers is
not recommended. Wiring should be performed by qualified personnel in accordance with all applicable
national, state and local electrical codes.
Flammable or Explosive Applications: Sensor mount controllers should not be used with explosive or
flammable liquids, which require an intrinsically safe or explosion proof rating. If you are unsure of the
suitability of a controller for your installation, consult your Flowline representative for further information.
Install In a Dry Location: The LC10 & LC11 Series controller housing is liquid-resistant and made of
Polypropylene (PP). When installed properly, the controller is not designed to be immersed. It should be
mounted in such a way that it does not normally come into contact with fluid. Refer to an industry
reference to ensure that compounds that may splash onto the controller housing will not damage it. Such
damage is not covered by the warranty.
Relay Contact Rating: The relay is rated for a 16 amp (12 amp – CE version) resistive load. Many loads
(such as a motor during start-up or incandescent lights) are reactive and may have an inrush current
characteristic that may be 10 to 20 times their steady-state load rating. The use of a contact protection
circuit may be necessary for your installation if the 16 amp rating does not provide an ample margin for
such inrush currents.
Safety Cover: Based upon the part number selected, a safety cover has been placed within the enclosure.
Always replace the safety cover after any service.
